NEW BEDFORD - Police are investigating after a man tried to get away with an entire cash register instead of just its contents Thursday night in New Bedford.

The clerk told police the man walked into Wessam Variety on Acushnet Avenue at 9 p.m. Thursday, pulled out a knife and demanded money. The suspect then grabbed the register and tried to take it, but ended up running out of the store without anything.

The clerk chased the suspect down Shaw Street, but lost sight of him.

A grey, older model Honda may have been used by the suspect.

Police are investigating. Anyone with information on the robbery is asked to call New Bedford Police at 508-991-6350 or the anonymous tip line at 508-992-7463 or e-mail tip@newbedfordpd.com.
